CCR field - from Dave Engebretsen

pagecache changes.

   This patch has been floating inside IBM for a bit, but it appears
that no one passed it back up to you, yet.  I don't know who wrote it,
but it applies to 2.5.8 and the ServeRAID driver works just fine with it
applied.  Without it, the driver fails to compile.

Here is the patch to add the arch_consoles_callable() macro as was done
in the 2.4 tree.

This is the patch to add support for PR_SET_FPEMU/PR_GET_FPEMU to give
per-process control over fp-emulation handling.  It also cleans up the
way PR_SET_UNALIGN_CTL/PR_GET_UNALIGN_CTL are implemented.

Randy observed that 2.5 /proc/meminfo SwapFree holds steady
while SwapTotal goes up and down: wrong way round!

Andrew pointed to wrong conditional in si_swapinfo(): 2.5.4
updated it incorrectly when new flags bit was briefly added.
And pointed out that it also makes si_swapinfo much too slow.

The obvious patch to fix compiler warning when compiled with RH gcc 2.96
(and probably others too).

Finally, this changes set_bit et al. to take a "unsigned long *" on
ppc and i386.  This will make the world a better place.

Please forward patches for any warnings which crop up in random code
to trivial@rustcorp.com.au.

We have to include linux/bitops.h for arch using generic_xxx().

The following patch changes <asm/bitops.h> of include/linux/* to
<linux/bitops.h>.

Note patch compiles but is otherwise untested as no kernel after 2.5.7
boots on my 2.5 box due to IDE hanging the box hard during device
discovery. )-:

- Don't abuse the sense field for passing failed packet_commands in struct
   packet_command use a new field instead.

- Apply minor bits forwarded by Dave Jones to me.

- Fix ide_raw_taskfile() to flag the ar used there to be no subject of free_req
   list management. This solvs the "hang after /proc/ide read" problem, which
   was in fact a memory corruption problem.

- Consolidate ide_choose_drive() and choose_drive() in to one function.

- Remove sector data byteswpapping support. Byte-swapping the data is supported
   on the file-system level where applicable.  Byte-swapped interfaces are
   supported on a lower level anyway. And finally it was used inconsistently.

- Eliminate taskfile_input_data() and taskfile_output_data(). This allowed us
   to split up ideproc and eliminate the ugly action switch as well as the
   corresponding defines.

- Remove tons of unnecessary typedefs from ide.h

- Prepate the PIO read write code for soon overhaul.

- Misc small bits here and there :-).

very minor cleanup only (I want all references to list-multi gone ;-)

remove some long obsolete boilerplate code.

We use the makefile variable $(foo-objs) to list the objects
a composed module foo.o is supposed to be composed of.

We use the special varible $(export-objs) to list the object files which
export symbols.

This oviously clashes in the case of foo == export. There's basically
two ways to handle it: (1) rename one of these options, like 
foo-objs to foo-parts or something, or (2) simply disallow a composite
object called export.o, so you never need $(export-objs) to list its
parts.

As (1) would affect basically all Makefiles in the tree and (2) doesn't
seem much of a limitation, I went for (2).

USB kaweth driver updates

	- fixed race between close and disconnect
	- disconnect bug
	- add link state reporting
	- fix an urb reference counting bug
	- fix probe oopsability on oom
	- groundwork for atomic pool depletion
	- cosmetic changes

This removes gratuitous & operators in front of USB's
dev->bus->devmap.devicemap and state->unitbitmap, for bitops.

This just makes it so it doesn't warn when set_bit et. al take a
long...

No object code changes,
Rusty.

Create "export_operations" interface for filesystems to describe
whether and how they should be exported.

- add new field in struct super_block "s_export_op" to describe
  how a filesystem is exported (i.e. how filehandles are mapped to
  dentries).
- New module: fs/exportfs for holding helper code for mapping between
  filehandles and dentries
- Change nfsd to use new interface if it exists.
- Change ext2 to provide new interface
- Add documention to filesystems/Exporting

If s_export_op isn't set, old mechanism still works, but it is
planned to remove old method and only use s_export_op.

Prepare for new export_operations interface (for filehandle lookup):

 - define d_splice_alias and d_alloc_anon.
 - define shrink_dcache_anon for removing anonymous dentries
 - modify d_move to work with anonymous dentries (IS_ROOT dentries)
 - modify d_find_alias to avoid anonymous dentries where possible
   as d_splice_alias and d_alloc_anon use this
 - put in place infrastructure for s_anon allocation and cleaning
 - replace a piece of code that is in nfsfh, reiserfs and fat
   with a call to d_alloc_anon
 - Rename DCACHE_NFSD_DISCONNECTED to DCACHE_DISCONNECTED
 - Add documentation at Documentation/filesystems/Exporting

Advansys SCSI driver update:
 - locking fixes
 - handle the "address" -> "page+offset" switch

Made urb allocation dynamic, as the USB core needs this now.

USB pegasus and rtl8150 fixes and improvements

pegasus:
	- using preallocated skb thus avoiding memcpy in the receive path;
	- tasklet used to handle failed skb allocations and Rx urb submission;
	- Lindent run on the result.

rtl8150:
	- better tasklet handling and a few races fixed;
	- introducing new flag for Rx urb resubmission;
	- GFP_KERNEL to GFP_ATOMIC flag change in Tx path.

A few (anal) comment cleanups and additions in relationship to the new
task cpu affinity syscalls.  All no brainers.

This fixes the mpparse.c clobbering the last ACPI patch did. Martin, look
OK? Again, my apologies.

This fixes a race in migration_thread which results in a deadlock on
boot for some SMP systems.  The fix is to to disable preemption inside
of set_cpus_allowed.

Andrew Morton first noticed the problem and provided the following patch
a few weeks back.  I was not affected until the recent migration_init
fix, for some odd reason.  Neither Andrew nor I think this is actually
kernel preemption's fault but perhaps a race in the tricky behavior of
the migration code.

This patch is the start of the cleanup of the fbdev layer. It has been
approved by Geert and has been tested for some time in the Dave Jones
tree.

Remove localy defined wait queues and use wait queues
in tty structure of same function. This matches the
n_tty.c behavior.

Handle pty hangup when blocked on read.

These 2 changes fix use of n_hdlc with PPPoATM and
are mirror changes included in 2.4.19-pre

patch to update virt_to_bus functions and remove version depedent #ifdef
statements

This is originally from Andrew in the 2.4 series, please apply for 2.5
as well.

Fix oops in st_open..
